Description
as of Drools 7.33.0.Final, forall patterns with "not equal" (!=) constraints will break when building the KieBase.
For example the following DRL:
rule "forall with not equal"
when forall(String(this != "foo"))
then
end
generates the following error:
java.lang.StringIndexOutOfBoundsException: String index out of range: -1

This is working fine when using Drools <= 7.32.0.Final.
